To all whom it may concern: i Be i-tlkriowi'i that I,;' EMIL A. NELSON, a citizen of. the United' States of America, vresidinor at Detroit, in the county of Vayne and btate of Michigan, h a'yev invented certain -newand' useful Improvements in Iiiduction-Conduits for Explosion-Engines, of which the following is a specification, reference being had ltherein vto the accompanyingdifawings.; v

It is the objecto theil'ivention to pio. vide a simple and compact construction of induction cond-uit .connecting the carbureter to the various cylinders ofainulti-cylinder engine, and-it is .a further' object to elfect the its passage V'through said "ccnduit."

-To this end, the invention consists ina.' construction as hereinafter set'forth.`

`In the drawings-.Figure Itis an elevation of the' induction conduit; 'Fig..2 is a longitudiiial section of the line aie-cv Fig. l; and, Fig. 3 is a horizontal section onI the lineg/-tj Fig. 1. In .the specicembodiment of my invention illustrated, the Vinduction'conduit is intended for application to a four-cylinder exin the engine casing, .each located between a' pair of cylinders. As both of thesefports are to be connected to the same carbureter, the induction conduit comprises a. main conduit A and two branch'conduits B B', prefranch conduits terminate' in flanged elbows C,

I) to the carbureter -E. When'secured in position on the engine casing, the portions 1*"-indicated in dotted lines, Fig. 2.

is a conduit *extending parallel to the conduit A and having a curved extension H let oft is conduit G' passes' around the ranches B -B".,aiid has a flanged mouth I of 'segexha'ust conduit F, but 'is spaced therefrom.

In 'operatioii,' the suction `of the engine will draw the air through the flanged mouth I around the exhaust` ipe'F, which will impart 'itshcat to the airbefoieit.enters'the conduit. .After passing through the car-` bureter, the explosive mixture returns v Y specin'cationo rette'rsr'a'tat.

arated' from the conduit Gr merely by the tliiiilwall J a portion of the heat of the in* coming air is imparted to the carbureted'air, which has been lowered in temperature. In the further movement ofthe mixture, it will 'pass' through the branch conduits B B, which lie adjacent to the exhaust condu-it F, and `are further heated therefrom.

The induction' conduit is' preferably formed of an integral castingfwhich may be easily attached or detached froin'the'engine casing. That I claim as my invention is: l. An induction conduit for ex losion engines, coinprising a T-slia ed casting having .complementary conduits ormedin the stem portion thereof forming inlet and outlet conthrough the conduit A, and, as this isjsepi nections `to the carbureter, and branch'con-` duitsfroni the outlet conduit formed in the T-portioii ofthe casting.

2. The combination with the exhaust con .duit of an explosionengine, of an induction conduit comprising a T-shaped casting having its cross portion lying in proximity and substantially parallel to the exhaust conduit, the stein portion ha ving two complementary conduits formed therein leading respectively to and from the cai'bureter, t'he latter conduit connecting with the branches in the cross portion, and the former being provided with a flange mouth adjacent the .exhaust conduit.

3. An induction conduit for explosion en- 1 gines, comprising a T-sliaped casting formed with branch conduits in the cross portion thereof, complementary conduits in the stein portion thereof, one being connected with .said branch conduits andthe other being open atits end adjacent the branch conduit, the lower ends of said complementary con- .duits beingconnected to 4the carbureter respectively at the center and 'bottom thereof.

4. In an induction conduit for explosion engines, the combination with a T-shap'ed casting `liavingthe end ot` the stern portion opposite the cross portion bent laterally, said stem portioncarrying complementary conduits formed therein leading respectively to and 'from the carbuieter,I and being con- 'nected with the latter at the' sid and bottom, and the cross portion of the "i" forming branch conduits connected wi conduit from the carbureter,
